Got a northern tool 16" surface cleaner rated at 3000 psi and 3gpm max. My only pressure washer avail now is a 3500 psi and 4 gpm. I can turn the pressure down to 3000 but will the 4gpm break the surface cleaner??

i was just worried about the bearing where the flex hose connects to the bushing that connects to the wand that has the nozzels on it. dunno what the effects of too much gpm would do to a homeowner surface cleaner. just want to use this one till I can warrant buying a commercial quality one.

do not change the pressure on the unloader, change the orfice tips and regulate the pressure that way
